Description

Technical Field

[0001] This utility model relates to the technical field of floor brush components, specifically a floor brush component that facilitates the replacement of roller brushes. Background Technology

[0002] In the widely used upright vacuum cleaners, canister vacuum cleaners, or cleaning machines, the floor brush is a crucial component. Connected to the main unit via a dust hose, it is primarily used for cleaning floors, carpets, and other surfaces. Existing floor brushes typically consist of a housing and a roller brush mounted on the housing. After the roller brush is installed, a cover plate is installed on the housing to secure it. Therefore, when replacing the roller brush, the cover plate must be removed first. However, the common method of installing the cover plate requires tools, such as screws, which necessitates a screwdriver for removal and installation, making the process inconvenient.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown, a floor brush assembly with a convenient roller brush replacement includes a floor brush body 1. Fixing blocks 2 are fixedly connected to both the front and rear ends of the right side of the floor brush body 1. A rotating groove 3 is formed on the inner side of the fixing block 2. A connecting rod 4 is rotatably connected inside the rotating groove 3. A roller brush 5 is rotatably connected inside the connecting rod 4. A connecting piece 6 is rotatably connected inside the fixing block 2. A limiting piece 7 is fixedly connected inside the connecting piece 6. A first sliding groove 8 is formed on the outer side of the rotating groove 3. The first sliding groove 8 and the connecting rod 4 are slidably connected to the limiting piece 7. A first groove 9 is formed on both the front and rear sides of the top of the floor brush body 1. A first moving block 10 is slidably connected inside the first groove 9. A limiting rod 11 is fixedly connected to the right side of the first moving block 10. The floor brush body 1 and the fixing block 2 are slidably connected to the limiting rod 11. A first limiting block 12 is fixedly connected to the top of the limiting piece 7. A first limiting groove 13 is formed inside the first limiting block 12. The first limiting groove 13 is slidably connected to the limiting rod 11.

[0021] refer to Figures 1 to 5 The top of the first moving block 10 is fixedly connected to the first pull block 14, which is slidably connected to the brush body 1. The left side of the first pull block 14 is fixedly connected to the first baffle 15 located above the first groove 9, which is slidably connected to the brush body 1. The top of the limiting rod 11 is fixedly connected to the connecting block 16, and the top of the connecting block 16 is fixedly connected to the second baffle 17 located above the rotating groove 3, which is slidably connected to the fixing block 2. The bottom of the first groove 9 is provided with an opening 18, which consists of several openings. The bottom of the first moving block 10 is provided with brush bristles.

[0022] As a technical optimization of this utility model, by setting a first pull block 14, a first baffle 15 and a second baffle 17, pulling the first pull block 14 can drive the first moving block 10 to move, which facilitates the separation of the limiting rod 11 and the first limiting block 12. The first baffle 15 is located above the first groove 9 and can block the top opening of the first groove 9 to prevent dust from entering the first groove 9. The first moving block 10 can scrape the dust in the first groove 9 through the through-hole 18. When the limiting rod 11 moves, it drives the second baffle 17 to move. The second baffle 17 can block the top of the rotating groove 3 to prevent dust from entering the rotating groove 3.

[0023] refer to Figures 1 to 5 A second pull block 19 is fixedly connected to the outer side of the connecting piece 6, and a second limiting block 20 is fixedly connected to the outer side of the fixing block 2. The second limiting block 20 is in contact with the second pull block 19.

[0024] As a technical optimization of this utility model, by setting a second pull block 19 and a second limiting block 20, the second pull block 19 facilitates the rotation of the connecting piece 6, and the second limiting block 20 can limit the rotation angle of the second pull block 19, so that it drives the limiting piece 7 to rotate directly above the connecting rod 4, and at the same time facilitates the alignment of the first limiting groove 13 and the limiting rod 11, so that the limiting rod 11 can be easily connected to the first limiting groove 13.

[0025] refer to Figures 1 to 5 The right side of the brush body 1 is provided with a first storage groove 21, and the left side of the rotating groove 3 is provided with a second storage groove 22.

[0026] As a technical optimization of this utility model, by setting a first storage groove 21 and a second storage groove 22, when the second baffle 17 moves to the left, it can be inserted into the first storage groove 21, and the fixing block 2 enters the second storage groove 22, to prevent the second baffle 17 from moving too far, which would make it difficult for the connecting rod 4 to move upward out of the rotating groove 3.

[0027] refer to Figures 1 to 5 The bottom of the limiting piece 7 is connected to a ball bearing 23, and the surface of the ball bearing 23 is in contact with the connecting rod 4.

[0028] As a technical optimization of this utility model, by setting the ball bearing 23, the connecting rod 4 at the bottom of the limiting piece 7 can be easily rotated, reducing the friction when the connecting rod 4 rotates.

[0029] refer to Figures 1 to 5 A spring 24 is fixedly connected inside the first groove 9, and one end of the spring 24 is fixedly connected to the first moving block 10.

[0030] As a technical optimization of this utility model, by setting a spring 24, the spring 24 can automatically push the first moving block 10 to move in the right direction, so that it pushes the limiting rod 11 to connect with the first limiting block 12, thereby increasing the stability when the limiting rod 11 is connected with the first limiting groove 13.

[0031] The working principle and usage process of this utility model are as follows: When the roller brush 5 needs to be disassembled, pull the first pull block 14 to the left. The first pull block 14 drives the first baffle 15 and the first moving block 10 to move. The first moving block 10 drives the second baffle 17 to move, so that it passes through the first limiting groove 13 and separates from the first fixing block 2. This causes the limiting rod 11 to separate from the first limiting block 12. At the same time, the limiting rod 11 drives the connecting block 16 to move, so that it is inserted into the second receiving groove 22. The connecting block 16 drives the second baffle 17 to move, so that the second baffle 17 is inserted into the first receiving groove 21. The connecting piece 6 can be rotated by the second pull block 19. The connecting piece 6 drives the limiting piece 7 and the first fixing block 2 to rotate into the first sliding groove 8. When the limiting piece 7 is inserted into the first sliding groove 8, the roller brush 5 can be moved upward. The roller brush 5 drives the connecting rod 4 to move out of the rotating groove 3. After the roller brush 5 is disassembled, the first pull block 14 is pulled to put the connecting rod 4 into the rotating groove 3. The second pull block 19 is reversed to make it contact the second limiting block 20. The second pull block 19 drives the connecting piece 6 to rotate. The connecting piece 6 drives the limiting piece 7 to rotate above the connecting rod 4. The spring 24 pushes the first moving block 10 to drive the limiting rod 11 to insert into the first limiting groove 13, and the connecting rod 4 is positioned.
